Backing Up The Startup Configuration File; Deleting The Startup Configuration File For The Next Startup - 3Com 4500G Family Configuration Manual

A configuration file must use .cfg as its extension name and the startup configuration file must be saved
under the root directory of the storage medium.

Backing Up the Startup Configuration File

The backup function allows you to copy the startup configuration file to be used at the next system
startup from the device to the TFTP server for backup.
The backup operation backs up the startup configuration file to the TFTP server for devices supporting
main/backup startup configuration file.
Follow the step below to back up the startup configuration file to be used at the next system startup:
To do...
Back up the configuration file to
be used at the next system
startup to the specified TFTP
server
Before the backup operation, you should:
Ensure that the server is reachable, the server is enabled with TFTP service, and the client has
permission to read and write.
Use the display startup command (in user view) to see whether you have set the startup
configuration file. If the file is set as NULL or does not exist, the backup operation will fail.

Deleting the Startup Configuration File for the Next Startup

You can delete the startup configuration file to be used at the next system startup using commands. You
can choose to delete either the main or backup startup configuration file. However, in the case that the
main and backup startup configuration files are the same, if you perform the delete operation for once,
the system will not delete the configuration file but only set the corresponding startup configuration file
(main or backup, according to which one you specified in the command) to NULL.
You may need to delete the startup configuration file for the next startup for one of these reasons:
After you upgrade system software, the existing configuration file does not match the new system
software.
The configuration file is corrupted (often caused by loading a wrong configuration file).
After the startup configuration file is deleted, the system will use the null configuration when the device
reboots.
Follow the step below to delete the startup configuration file for the next startup:
Use the command...
backup startup-configuration
to dest-addr [dest- filename ]
